United States Patent CONTAINER ARRANGED WITH A SPOUT IN ONE END Robert Nyden, Manhasset, N. Y., assignor, by direct and mesne assignments, to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application September 26, 1952, Serial No. 311,612

11 'Claims. (Cl. 2'22-569) This invention relates to a container arranged with a spout in an end wall of the container adapted to dispense liquids, such as lubricating oil, lighter fluid and the like, andlparticularly to securing the spout in the container end wal The present invention is an improvement over applicants pending application Serial No. 183,741 filed September 8, 1950, whereby the necessity of a sealing gasket has been eliminated and a double liquid-seal, is provided between the spout and the end wall of the container.

The present invention is also particularly'adapted for use of a pouring spout of pliable material, such as polyethylene, whereby the spout is readilyforced into sealing engagement with the material of the container and said sealing engagement is maintained under the inherent force of the material of the spout.

Other advantages of the invention will be set forth in the detailed description of the invention. l

In the drawing accompanying and forming a part of this application:

Figure 1 is a top view of a container and aspout sealed therein.

Figure 2 is an elevational view of the container with the upper portion of the container and spout in section taken on the line 22 of Figure 1 looking in the direction of the arrows.

Figure 3 is a longitudinal-sectional view of a spout.

Figure 4 is a longitudinal-sectional view of .a modified form of spout. I

The invention relates to a sheet metal container body including side walls 5 and end walls 6 and 7 secured to the opposite ends of the side walls in a liquid-tight seal, as shown in Figures 1 and 2.

The embodiment of the invention comprises in part a boss 8 arranged in the end wall 6 constituting the top of the container and having diametrically opposite portions adjacent to opposite side walls of the container, as shown at 9 in Figures 1 and 2, for a purpose to be hereinafter described. The boss 8 is provided with a depressed portion having an inwardly extending annular lip 10 at the juncture thereof with the boss and an annular recess 11 in the side wall adjacent to a bottom wall 12, as shown in Figure 2. The recess 11 is of curved form in cross section. The bottom wall 12 is provided with a center opening formed by an annular flange or skirt 13 tapering from the bottom wall into the container body and the juncture between the bottom wall and flange being rounded, as at 14 in Figure 2, for a purpose to be hereinafter described.

The other part of the .invention consists of a spout of pliable material, such as polyethylene, including a tapering body portion 15 having the smaller end closed and weakened, as at 16, to be punctured by a pin to form a dispensing opening. The larger end of the body portion 15 is formed with an integral shoulder 17 of a diameter slightly larger than the diameter of the recess 11 of the depressed portion to form a liquid-tight seal between said shoulder, and the lip 10 and recess 11 of the depressed portion. The upper surface of the shoulder 17 is inclined from the periphery of the shoulder to the body portion 15, as shown at 18, and the periphery of the shoulder is rounded corresponding to the curvature of the recess 11, as shown at 19 in'Figure 3. The end portion of the spout below the shoulder 17 is of cylindrical form, as shown at 20 in Figure 3, of greater diameter than the spout body 15 and having a straight side'with a bevel 21 at the outer side of the end. The outer diameter of the cylindrical portion 20 is substantially the'same as the opening in the larger end of the tapering flange 13;

' In assembling the spout 1521 in the depressed portion 1013, the spout is placed in a tubular plunger, not shown, having a head engaging the inclining or sloping surface 18. The plunger forces the shoulder 17 past the lip 10 into the recess 11 and the lower end'section of the cylindrical portion 20 past the smaller end of the tapering flange 13. The pliability of the material of the spout permits the shoulder 17 to pass the lip 10 and the cylindrical portion 20 to pass the smaller end of the tapering flange 13. Also the rounded periphery 19 facilitates passage of the shoulder into the recess 11 and the rounded juncture 14 and the bevel 21 facilitate passage of the cylindrical portion 20 into the tapering flange 13. The taper of the flange 13 will also facilitate passing of the cylindrical portion.

The pliability of the material of the spout also forms a liquid-tight seal between the rounded shoulder periphery 19 and the recess 11.

The rigidity of the flange 13 and the pliability of the material of the spout will cause the end section of the cylindrical portion 20 projecting below the flange 13 to bulge outwardly and form a bulbous portion 22, as shown in Figure 2, which forms a liquid-tight seal with the smaller end of the flange 13 and locks the spout in the depressed portion. The forming of the bulbous portion 22 will cause the end portion of the bore ofJthe cylindrical portion20 to be deformed, as shown :at' 23 in Figure 2.

The boss 8 stiifens the container end wall 6 and prevents collapsing of said end wall when pressure is applied to the spout in assembling the spout in the depressed portion.

The lip 10 will prevent-canting of the spout assembled in the depressed portion which canting may cause leakage at the liquid-tight seals.

Figure 4 shows a modified form of spout of pliable material comprising a tapering body portion 24 similar to the body portion 15, 16 and a cylindrical portion 25 similar to the cylindrical portion 20, 21. Between the body portion 24 and cylindrical portion 25, there is provided a shoulder 26 declining from the body portion 24 at an acute angle to the cylindrical portion 25. The periphery of the shoulder 26 is rounded, as at 27, for the same purpose as the rounded periphery 19 and the diameter of the shoulder at said periphery is substantially the same as the diameter of the opening formed by the lip 10 so that the shoulder may readily enter the depression recess 11 and the downward movement of the assembling plunger will. flatten the shoulder 26 into a tight fit with the depression recess 11 to form a liquid-tightseal therewith in the same manner as the shoulder 17 shown in Figure 2. The shoulder 26 extends at such an angle to the cylindrical portion so that the diameter of the shoulder in flattened condition is slightly greater than the diameter of the recess 11; The flattening of the shoulder 26 .into the recess 11 will place a'tension on the shoulder and create a greater seal with the recess 11 than the shoulder 17.

Having thus described my invention, I claim:
